Browse Project Baselines and show Plan Comparison View

Modified on Sun, 02 May 2021 at 03:04 PM

Goal: We want to be able to show a comparision of current plan to a polarion baseline that user selects.

Gantt Configuration

1) On a Gantt report page (the page where you have your Nextedy GANTT chart), create a page parameter "baselineRevision" of type "string":

2) Put the following script into Gantt Widget properties > Advanced > Item script:

(It loads the baseline data from the historical object, using the UTIL methods getDate and getDuration)

var revision = config.getPageParameters().get("baselineRevision");

if(revision && revision.length>0){
  var origWi = wi.getDataSvc().getVersionedInstance(wi.uri,revision);
  task.planned_start_date=util.getDate(origWi, "start");
  task.planned_duration=util.getDuration(origWi, "initialEstimate")
}

Be careful that the name of fields (in our case "start" and "initialEstimate") must match your mapping section, in our case we have in mapping section "start" and "initialEstimate", so we use these two fields.

Baseline Portal Page

Now let's create a sample page that shows the project baselines, and let us open a Gantt that shows the difference between current plan and baseline. You can put the same code on any of your project index pages).

Create a new live report page and put the a snippet. Please: adjust the ganttPagePath to your Gantt report page...

#set($projectId = $page.reference.projectId)

### Adjust to your gantt page path
#set($ganttPagePath="/project/$projectId/wiki/Planning/Gantt")

#set($project = $trackerService.getTrackerProject($projectId))

<ul>
#foreach($b in $project.baselinesManager.baselines)
   <li>
   <a target="_blank" href="/polarion/#$ganttPagePath?baselineRevision=$b.getBaseRevision()">
	   	<b>$b.name </b> - $b.getBaseRevision()
   	</a>
   	<br> $b.baseRevisionObject.created <br><br>
   </li>
#end
</ul>

You will have something like:

You can now click on the revision on this page and open a current Gantt compared to any historical revision.
